Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.

First, an application scenario of the present disclosure will be explained. The disclosure can be applied to 5G network, and compared to 4G (The 4th Generation Mobile Communication Technology, fourth Generation Mobile Communication Technology), a very important characteristic of 5G is ultra-low latency in data transmission, so that The importance of latency, an index, in measuring network performance, is significantly increased.

The definition of the user plane air interface delay and the delay requirements of URLLC service and eMBB service are given by 3GPP (3rd Generation Partnership Project), which includes: for URLLC, the target delay of the user plane should be 0.5ms for UL (uplink) and 0.5ms for DL (downlink); for the eMBB, the UL user plane delay target is 4ms and the DL is 4 ms. The user plane air interface delay can be considered as the delay spent by the application layer data packet from the SDAP layer of the sending end to the SDAP layer of the receiving end to be successfully received.

However, in the related art, the delay optimization of the service layer is not performed in the wireless network for different service types, so that when the discard time configuration of the PDCP layer is not reasonable, the problem of wasting transmission resources or prematurely discarding part of data packets may be caused, and thus the efficiency of data transmission is low.

In order to solve the above problems, the present disclosure provides a method, an apparatus, a storage medium, a network device, and a terminal for scheduling a terminal device, where the network device may adjust a scheduling priority of the terminal device according to a first processing delay and a second processing delay sent by the terminal device, and then may schedule the terminal device with the highest scheduling priority, so that a target scheduling priority adjusted according to a priority adjustment amount is more accurate, so that when the network device schedules the terminal device according to the target scheduling priority, it may be avoided that a data packet with a higher scheduling priority is not scheduled in time and is discarded too early, or a waste of transmission resources is caused in a process of waiting for transmission of a data packet with a lower scheduling priority, thereby improving efficiency of data transmission.

The present disclosure is described below with reference to specific examples.

Fig. 1 is a flowchart of a method for scheduling a terminal device according to an embodiment of the present disclosure, where the method is applied to a network device, and the network device may be an NR (New Radio) base station. As shown in fig. 1, the method includes:

s101, receiving a first processing time delay and a second processing time delay sent by a plurality of terminal devices.

The first processing delay may include a processing delay of the data packet at the SDAP layer of the terminal side, and the second processing delay may include a processing delay of the data packet from the RLC layer to the physical PHY layer of the terminal side. The plurality of terminal devices may include terminal devices corresponding to all scheduling requests received by the network device at the current time.

In this step, the first processing delay and the second processing delay may be obtained in advance by the terminal device, and when the terminal device sends a service request message to the network device, the first processing delay and the second processing delay may be carried in the service request message.

And S102, aiming at each terminal device in the plurality of terminal devices, acquiring a priority adjustment amount corresponding to the terminal device according to the first processing time delay and the second processing time delay, and adjusting the scheduling priority of the terminal device according to the priority adjustment amount to obtain an adjusted target scheduling priority.

The scheduling priority may represent an order in which the network device schedules the terminal device, and the network device may schedule the terminal device according to the order from high to low of the scheduling priority when scheduling the terminal device.

In this step, after receiving the first processing delay and the second processing delay sent by the terminal device, the priority adjustment amount corresponding to the terminal device may be obtained according to the first processing delay and the second processing delay. Since there may be a plurality of terminal devices that send the service request message to the network device, after the priority adjustment amount corresponding to each terminal device is obtained, the scheduling priorities of all terminal devices may be adjusted according to the priority adjustment amount, so as to obtain the adjusted target scheduling priority.

And S103, scheduling the terminal equipment with the highest target scheduling priority in the plurality of terminal equipment.

In this step, after the adjusted target scheduling priorities of the plurality of terminal devices are obtained, the terminal device with the highest target scheduling priority among the plurality of terminal devices may be scheduled.

By adopting the method, the network equipment can adjust the scheduling priority of the terminal equipment according to the first processing time delay and the second processing time delay sent by the terminal equipment, and then the terminal equipment with the highest scheduling priority can be scheduled, so that the target scheduling priority adjusted according to the priority adjustment quantity is more accurate, and when the network equipment schedules the terminal equipment according to the target scheduling priority, the data packet with higher scheduling priority can be prevented from being discarded too early because the data packet is not scheduled in time, or the waste of transmission resources caused in the process of waiting for transmitting the data packet with lower scheduling priority can be avoided, thereby improving the efficiency of data transmission.

Fig. 2 is a flowchart of a second method for scheduling a terminal device, which is applied to the terminal device according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:

s201, determining a first processing time delay and a second processing time delay.

The first processing delay may include a processing delay of the data packet at an SDAP layer of the terminal side, and the second processing delay may include a processing delay of the data packet from an RLC layer to a PHY layer of the terminal side.

In this step, before the terminal device sends the service request message to the network device, the first processing delay and the second processing delay may be predetermined. When the first processing delay is determined, timing may be started when a data packet reaches an SDAP layer on a terminal side, and timing is ended when processing of the SDAP layer is completed, where the timing period is the first processing delay, and the first processing delay may represent processing capability of the terminal device. After the first processing delay is determined, the second processing delay stored in advance may be obtained, where the second processing delay may be a delay configured in advance and within a delay range specified by a communication protocol, and the second processing delay may be stored in advance in the network management device or in the terminal device, which is not limited in this disclosure.

S202, the first processing time delay and the second processing time delay are sent to network equipment.

In this step, after determining the first processing delay and the second processing delay, the first processing delay and the second processing delay may be sent when sending a service request message to the network device. After receiving the first processing delay and the second processing delay sent by the terminal device, the network device obtains, for each terminal device in the plurality of terminal devices, a priority adjustment amount corresponding to the terminal device according to the first processing delay and the second processing delay, adjusts the scheduling priority of the terminal device according to the priority adjustment amount, obtains an adjusted target scheduling priority, and schedules the terminal device with the highest target scheduling priority in the plurality of terminal devices.

By adopting the method, the terminal equipment can firstly determine the first processing time delay of the data packet at the SDAP layer of the terminal side and the second processing time delay of the data packet from the RLC layer to the PHY layer of the terminal side, and send the first processing time delay and the second processing time delay to the network equipment, the network equipment can adjust the scheduling priority of the terminal equipment according to the first processing time delay and the second processing time delay sent by the terminal equipment, and then can schedule the terminal equipment with the highest scheduling priority, so that the target scheduling priority adjusted according to the priority adjustment quantity is more accurate, and when the network equipment schedules the terminal equipment according to the target scheduling priority, the data packet with higher scheduling priority can be prevented from being discarded too early because of not being scheduled in time, or transmission resources are prevented from being wasted in the process of waiting for transmitting the data packet with lower scheduling priority, so that the efficiency of data transmission can be improved.

Fig. 3 is a flowchart of a third method for scheduling a terminal device according to an embodiment of the present disclosure. As shown in fig. 3, the method includes:

s301, the terminal device determines a first processing time delay and a second processing time delay.

The first processing delay may include a processing delay of the data packet at an SDAP layer of the terminal side, and the second processing delay may include a processing delay of the data packet from an RLC layer to a PHY layer of the terminal side. Fig. 4 is a schematic diagram of data transmission provided in an embodiment of the present disclosure, as shown in fig. 4, the left side is from the SPAD layer to the PHY layer corresponding to the terminal side, and the right side is from the SPAD layer to the PHY layer corresponding to the network side, when the terminal device sends a data packet to the network device, the data packet is transmitted from the SPAD layer to the PHY layer on the terminal side, after the PHY layer is processed, the data packet is transmitted to the PHY layer on the network side, and the processing of the data packet is completed through the PHY layer to the SPAD layer on the network side. Wherein t1 is the first processing latency and t3 is the second processing latency.

S302, the terminal device sends the first processing time delay and the second processing time delay to the network device.

S303, after receiving the first processing delay and the second processing delay sent by the terminal device, the network device obtains a transmission discard time threshold of a PDCP layer configured for the terminal device by the network device according to the first processing delay and the second processing delay.

In this step, after receiving the first processing delay and the second processing delay sent by the terminal device, the network device may first obtain a transmission discard time threshold of a PDCP layer configured for the terminal device by the network device. The transmission discard time threshold may be obtained through steps S1 to S4:

and S1, acquiring the data transmission time delay and presetting a third processing time delay.

The data transmission delay may include a transmission delay between the terminal device and the network device, where the data transmission delay is related to a distance between the terminal device and the network device, and the larger the distance between the terminal device and the network device is, the larger the data transmission delay is, the smaller the distance between the terminal device and the network device is, and the smaller the data transmission delay is; the third processing delay may include a processing delay of the packet from the PHY layer to the SDAP layer on the network side. As shown in fig. 4, t4 is the data transmission delay, and t5 is the third processing delay.

Here, the manner of obtaining the data transmission delay includes multiple manners, and in a possible implementation manner, the time advance configured by the network device for the terminal device may be obtained, and the data transmission delay may be determined according to the time advance. The network device may calculate the time advance according to the location of the terminal device by means of a correlation technique, and use one half of the time advance as the data transmission delay.

In addition, after receiving the service request message sent by the terminal device, the network device may add a start time tag to the data packet corresponding to the service request message at a PHY layer of the network side, and add an end time tag after the service request message is transmitted to an SDAP layer of the network side, where a time interval between the end time tag and the start time tag is the third processing delay.

It should be noted that, after receiving the service request message sent by the terminal device, the network device may also start timing when the service request message reaches the PHY layer of the network side, and end timing after the SDAP layer of the network side completes processing of the service request message, where the timing time period is the third processing delay.

And S2, acquiring the fourth processing time delay of the service connection requested by the terminal equipment in the wireless network.

In a possible implementation manner, the network device may obtain a delay requirement corresponding to the service connection requested by the terminal device, obtain a core network transmission processing delay, and use a difference between the delay requirement and the core network transmission processing delay as the fourth processing delay.

Wherein, the delay requirement corresponding to the service connection may be carried in a service request message sent by the terminal device; the network device may also obtain the delay requirement from a core network, where the delay requirement may be determined by the core network according to the type of the service request message, and different service connections correspond to different delay requirements. The present disclosure may also obtain the time delay requirement corresponding to the service connection requested by the terminal device through other manners in the related art, which is not limited in the present disclosure.

Further, after determining the delay requirement corresponding to the service connection requested by the terminal device, the network device may send a delay obtaining request to a core network, where the delay obtaining request is used to obtain the core network transmission processing delay required by the core network to process the service connection. Then, the network device may obtain a difference between the delay requirement and the transmission processing delay of the core network, and use the difference as the fourth processing delay.

S3, obtaining a sum of the first processing delay, the second processing delay, the third processing delay and the data transmission delay.

After the network device receives the first processing delay and the second processing delay sent by the terminal device and obtains the third processing delay and the fourth processing delay, the sum of the first processing delay, the second processing delay, the third processing delay, and the data transmission delay may be obtained.

S4, taking the difference between the fourth processing delay and the sum as the transmission discard time threshold.

After the network device obtains the sum of the fourth processing delay, the first processing delay, the second processing delay, the third processing delay, and the data transmission delay, a difference between the fourth processing delay and the sum may be obtained, and the difference is used as the transmission discard time threshold.

It should be noted that, after obtaining the transmission discard time threshold, the network device may send the transmission discard time threshold to the terminal device, and after receiving the transmission discard time threshold sent by the network device, the terminal device may determine whether the waiting time of the to-be-transmitted data packet on the PDCP layer is greater than the transmission discard time threshold, and discard the to-be-transmitted data packet when determining that the waiting time of the to-be-transmitted data packet on the PDCP layer is greater than the transmission discard time threshold.

The network device may send the transmission discard time threshold to the terminal device through an RRC (Radio Resource Control) signaling, may send the transmission discard time threshold to the terminal device by using DCI (Downlink Control Information) format x in a PDCCH (Physical Downlink Control Channel), and may send the transmission discard time threshold to the terminal device through a MAC CE.

The terminal device may obtain the transmission waiting time of the data packet to be transmitted on the PDCP layer after receiving the transmission discard time threshold sent by the network device, and may discard the data packet to be transmitted when the transmission waiting time is greater than the transmission discard time. In addition, after discarding the data packet to be transmitted, the terminal device may supplement a new data packet as the data packet to be transmitted. Therefore, the transmission discarding time threshold can be adjusted according to the type of the service connection, so that the waste of transmission resources or the early discarding of data packets caused by unreasonable setting of the transmission discarding time threshold is avoided, and the efficiency of data transmission can be improved.

S304, the network equipment obtains the transmission waiting time delay of the data packet at the PDCP layer of the terminal side.

Wherein the transmission waiting delay may include a delay generated when the data packet is queued at the PDCP layer.

In this step, after the PDCP layer at the terminal side processes the data packet, the data packet is continuously transmitted to the RLC layer at the terminal side, and so on, and after the terminal side processes the data packet, the data packet is transmitted to the network device, so that the network device can determine the transmission waiting delay according to the time interval of scheduling the terminal device twice, as shown in fig. 4, t2 is the transmission waiting delay.

In a possible implementation manner, the network device may obtain a first time when the first processing delay is received, obtain a second time when the terminal device is last scheduled, and use a time interval between the first time and the second time as the transmission waiting delay. The second time of last scheduling the terminal device includes the time of last scheduling the network device by a data packet of the terminal device. After receiving the first processing delay sent by the terminal device, the network device may record current time, where the current time is the first time, and then may obtain a second time at which the terminal device was last scheduled, and use a time interval between the first time and the second time as the transmission waiting delay.

S305, the network device determines a priority adjustment amount according to the transmission discard time threshold and the transmission waiting time delay.

In this step, after obtaining the transmission discard time threshold and the transmission waiting delay, the network device may calculate the priority adjustment amount according to formula (1):

P _k ＝∑T _i /T _k (1)

wherein, P _k For the corresponding priority adjustment amount, sigma T, of the kth terminal equipment _i The sum of the weights, T, of the representations of the urgency of delay corresponding to a plurality of terminal equipments _k And the weight value is represented by the urgency of time delay corresponding to the kth terminal device.

For example, if the number of the terminal devices includes 10, taking the example that the network device obtains the priority adjustment amount corresponding to the 3rd terminal device, the network device may first obtain the weight T of the urgency-to-delay characterization corresponding to the 1 st terminal device ₁ The weight T of the urgency of delay characterization corresponding to the 2 nd terminal device ₂ The weight T of the urgency of delay characterization corresponding to the 3rd terminal device ₃ And by analogy, obtaining the weight T of the time delay urgency representation corresponding to the 10 th terminal device ₁₀ Then, the priority adjustment amount P corresponding to the 3rd terminal device can be calculated according to the formula (1) ₃ . The urgency of delay represents an urgency that a delay is about to expire, and for example, the shorter the time from the expiration of the delay, the larger the weight of the urgency of delay representation, and the longer the time from the expiration of the delay, the smaller the weight of the urgency of delay representation.

In addition, a weight value of the urgency of delay representation corresponding to the kth terminal device may be calculated according to formula (2):

wherein, T _k The weight value of the representation of the urgency of delay corresponding to the kth terminal device,

waiting for the transmission corresponding to the kth terminal device,

and the transmission discarding time threshold corresponding to the kth terminal device.

S306, the network equipment adjusts the scheduling priority of the terminal equipment according to the priority adjustment quantity to obtain the adjusted target scheduling priority.

In this step, after acquiring the priority adjustment amount corresponding to each terminal device in the plurality of terminal devices, the network device may use the priority adjustment amount as a weighted value of the scheduling priority, and adjust the scheduling priority of the terminal device according to the weighted value, so as to obtain an adjusted target scheduling priority. For example, when the scheduling priority of the terminal device is calculated, the priority adjustment amount may be superimposed in a calculation formula of the scheduling priority, so that the scheduling priority of the terminal device may be adjusted according to the urgency of delay of the terminal device, so that the network device may preferentially schedule the terminal device whose delay is about to expire, thereby avoiding waste of transmission resources.

S307, the network equipment schedules the terminal equipment with the highest target scheduling priority in the plurality of terminal equipment.

By adopting the method, the transmission discarding time threshold value acquired by the network equipment is associated with the service connection requested by the terminal equipment, so that the network equipment can adjust the transmission discarding time threshold value of the PDCP layer at the terminal side according to the requirement of the service layer, and the waste of transmission resources or the early discarding of data packets is avoided. Further, the network device may determine a priority adjustment amount according to the transmission discard time threshold and the transmission waiting time delay, adjust the scheduling priority of the terminal device according to the priority adjustment amount, obtain an adjusted target scheduling priority, and schedule the terminal device with the highest target scheduling priority among the plurality of terminal devices. Therefore, the network equipment can schedule the delay sensitive service preferentially, so that the delay sensitive service can be transmitted more quickly, and the data transmission efficiency can be improved.
